  • Patent number: 11183448
    Abstract: A wiring circuit board includes a first insulating layer, a terminal, a second insulating layer disposed at one side in a thickness direction of the terminal, and a wire continuous to the terminal in a direction crossing the thickness direction. The first insulating layer has an opening portion passing through the first insulating layer in the thickness direction and having the opening cross-sectional area increasing as being closer to one side in the thickness direction. The terminal has a peripheral end portion and a solid portion. The peripheral end portion contacts with an inner side surface of the first insulating layer. The inner side surface forms the opening portion. The solid portion integrally disposed with the peripheral end portion at the inner side of the peripheral end portion. The peripheral end portion and the solid portion fill the entire opening portion.
